A non-pneumatic tire having a rim member 1, a ring member 3 disposed at an outer circumferential side of the rim member 1 and provided with a tread 2 on a circumferential face, and a plurality of link mechanisms 4 coupling the rim member with the ring member. Each of the link mechanisms 4 contains a pair of link members 7a, 7b formed of a link 5a, 5b which is connected at a first end with a side portion of the rim member 1 and which is swingable in the circumferential and meridian directions and another link 6a, 6b which is connected at a first end with a side portion of the ring member and 3 which is swingable in the circumferential and meridian directions with second ends of the links being hingedly connected one another to make the links swingable in the meridian direction. A spring member 9 imparting a stiffness against relative displacements in the radian, circumferential and width directions with respect to the rim and ring members 1, 3 is provided on the link mechanisms 4.
